Batı Anadolu eski ve yeni bal arısı örneklerinin kanat morfolojisi farklılaşmasının geometrik morfometri kullanılarak belirlenmesi]

In this study, old and recent honey bee, Apis mellifera L., 1758 (Hymenoptera: Apidae) specimens were compared using geometric morphometrics. The old honey bee samples were collected from different apiaries in Edirne, Balıkesir, Çanakkale, Denizli and Muğla Provinces, and Gökçeada (an Aegean island) in Turkey in 1987-1988 under a project of the Aegean Agricultural Research Institute and the recent samples were collected in the same locations in 2017. The mean values determined for each region were grouped using Mahalanobis distances, and the results were summarized on dendrogram. While the old samples constituted one group, the recent samples constituted another one. When the results of the discriminant function analysis were compared, it was observed that overall old and recent samples were statistically different from each other (P < 0.0001). The evaluation of both groups has revealed that the recent population of Gökçeada was different from morphologically the other mainland populations in the current situation. However, the Thrace (Edirne) honey bee specimens were different from the Anatolian (Çanakkale, Denizli, Balıkesir, Muğla) and island (Gökçeada) specimens in the past according to dendrogram relationships. © 2021 Entomological Society of Turkey.

Normal neonatal electroencephalography and maturation of electroencephalography during neonatal period

Despite evolving technologies, electroencephalography (EEG) remains a powerful tool for neurological diagnosis and prognosis in both preterm and term neonates. Neonatal EEG is different from children and adult's EEG technically and also because it changes week by week as a result of brain maturation and growth. An EEG finding normal in a developmental stage may be abnormal in a different developmental stage owing to these rapid changes of brain growth. So it is important to know normal patterns of neonatal EEG in different conceptional weeks and behavioral states (sleep, awakeness). In this section, technical and qualitative features of normal neonatal EEG will be mentioned, normal graphoelements and maturational changes on the EEG background of neonates going through preterm to term age will be described
